Four coordinated products for glass cleaning, washer fluid, and window sealing – from quick interim cleaning to ceramic long-term protection, each developed for interior and exterior windows.\u003c\/em\u003e\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003cp\u003e\u003cstrong\u003eSONAX XTREME Window Care\u003c\/strong\u003e is not a haphazard assortment, but a well-thought-out system for all glass surfaces on a vehicle. With the XTREME series, SONAX has developed four complementary products: from glass cleaner for quick interim cleaning, two washer fluid variants for the windshield washer fluid reservoir, to ceramic glass sealant that combines cleaning and long-term protection in one step. The idea behind it: every window situation – be it insect residue in summer, salt haze in winter, or a greasy film on the inside window – requires the right chemical, not just more pressure on the cloth. Those who care for windows like paintwork – i.e., systematically instead of by chance – will be better off with the XTREME series in the long run.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFour products, one workflow.\u003c\/strong\u003e XTREME ScheibenKlar for manual cleaning, ScheibenReiniger Summer as ready-to-use washer fluid, ScheibenReiniger 1:100 as an economical concentrate, and Ceramic ScheibenKlar 2 in 1 as a cleaner with integrated ceramic sealant.

No product is superfluous, and none makes another redundant.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStreak-free results without re-polishing.\u003c\/strong\u003e The Pure-Water-Technology in the ScheibenKlar formula is based on demineralized water, which wets more evenly and dries without residue. No limescale, no streaks – not even on interior windows, where conventional cleaners often fail. The difference is particularly noticeable against glare: where other cleaners leave a milky haze, the window remains optically invisible.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProtection beyond cleaning.\u003c\/strong\u003e Special anti-resoiling components slow down re-soiling, and the Ceramic 2in1 technology builds up a hydrophobic protective layer with each application. This significantly extends the intervals between cleanings – a real time-saver, especially for frequent drivers.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003chr\u003e\n\n\u003cblockquote class=\"praxistipp\"\u003e\n  \u003cp\u003e\u003cstrong\u003ePractical tip from Detailing1:\u003c\/strong\u003e The most common mistake in window cleaning is using the wrong cloth. Paper towels leave fibers, old cotton rags scratch and only smear the dirt. Use a \u003ca href=\"\/products\/sonax-profiline-microfasertuch-glas-mikrofasertuch\" title=\"SONAX PROFILINE MicrofaserTuch Glas\"\u003eSONAX PROFILINE Microfiber Cloth \"Glass\"\u003c\/a\u003e – its short fibers absorb dirt and moisture without leaving residues. Spray the cleaner directly onto the window (not onto the cloth), spread with the wet side, and wipe with the dry side. One pass is enough. For the inside of the windshield, it is recommended to work with the door open – this way you can also reach the corners of the dashboard cleanly.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003ePure-Water-Technology and Ceramic 2in1 – the technologies behind the XTREME series\u003c\/h3\u003e\n\n\u003cp\u003eTwo technologies form the backbone of the SONAX XTREME Window \u0026 Glass range. The first is Pure-Water-Technology, used in \u003ca href=\"\/products\/sonax-xtreme-scheibenklar-glasreiniger\" title=\"SONAX XTREME ScheibenKlar Glasreiniger\"\u003eXTREME ScheibenKlar\u003c\/a\u003e: Instead of ordinary tap water, SONAX uses demineralized water as the basis of the cleaning formula. The difference may seem small at first glance, but it has a measurable effect – minerals like limescale and magnesium, which leave visible residues on the glass when drying, are completely absent. The cleaning formula wets the surface more evenly, dissolves grease films, nicotine deposits, and fingerprints more efficiently, and dries streak-free. The result is a window that you don't have to re-polish or wipe multiple times – one pass is enough to see no streaks, even in critical glare.\u003c\/p\u003e\n\n\u003cp\u003eThe advantage is particularly evident on interior windows: over weeks, a greasy film accumulates there from plastic outgassing from the dashboard, skin oils, and fine dust. Conventional tap water-based glass cleaners loosen this film, but redistribute it during drying – with limescale residues as a bonus. Pure-Water-Technology bypasses this problem because drying residues are simply eliminated. The glass not only becomes clean but truly clear. Drivers who frequently drive at dusk or at night immediately notice the difference: without a greasy film, there are no annoying light refractions from oncoming traffic, and the window \"disappears\" optically – you look through it, rather than at it.\u003c\/p\u003e\n\n\u003cp\u003eThe second key technology is found in \u003ca href=\"\/products\/sonax-xtreme-ceramic-scheibenklar-2-in-1-glasreiniger-versiegelung\" title=\"SONAX XTREME Ceramic ScheibenKlar 2 in 1\"\u003eXTREME Ceramic ScheibenKlar 2 in 1\u003c\/a\u003e: Here, SONAX combines a glass cleaner with silicon nanoparticles that polymerize on the glass surface during cleaning. While the cleaner dissolves dirt, the ceramic components simultaneously embed themselves in the uppermost microstructure of the glass surface. This creates a hydrophobic protective layer on which water droplets visibly bead off. This is not only visually impressive – the layer also reduces re-soiling because dust, pollen, and insect residues adhere less effectively. Unlike classic ceramic sealants, which require a multi-stage application with preparation cloths and curing times, Ceramic 2in1 technology works in a single step: spray on, rub in, let dry for five minutes – done.\u003c\/p\u003e\n\n\u003cp\u003eThe two washer fluid variants – \u003ca href=\"\/products\/sonax-xtreme-scheibenreiniger-sommer-wischwasser-gebrauchsfertig\" title=\"SONAX XTREME ScheibenReiniger Sommer\"\u003eScheibenReiniger Summer\u003c\/a\u003e and \u003ca href=\"\/products\/sonax-xtreme-scheibenreiniger-1-100-wischwasser-konzentrat\" title=\"SONAX XTREME ScheibenReiniger 1:100\"\u003eScheibenReiniger 1:100 Concentrate\u003c\/a\u003e – rely on a different strength: they combine cleaning power with glide protection for the windshield wipers and integrated corrosion protection for the washer nozzles and lines. The Summer cleaner comes ready-to-use and is optimized for insect residues, pollen, and road dust. The concentrate offers maximum flexibility and economy: 10 ml per 1 liter of water yields ready-to-use washer fluid – from a 250-ml bottle, you get up to 25 liters. In summer, with heavy insect contamination, you can increase the concentration to 1:80; in winter, the alcohol and glycol content provides frost protection down to sub-zero temperatures.\u003c\/p\u003e\n\n\u003cp\u003eWhat all four products have in common is material compatibility: SONAX has designed the XTREME formulas to be pH-neutral (between 6.5 and 7.5). This means they do not attack rubber seals, plastic surrounds, or special coatings on the glass. Vehicles with heat protection films, privacy glass, or tinted windows can also be treated without hesitation. This is not a self-evident standard – some aggressive glass cleaners can attack films and coatings over time if they contain alkaline ingredients.\u003c\/p\u003e\n\n\u003ch3\u003eWhich XTREME Window Product for Which Use – Range Navigator\u003c\/h3\u003e\n\n\u003cp\u003eThe four products in the XTREME series for windows and glass have clearly defined areas of application, and the choice depends on what you want to achieve and how often you care for your vehicle.\u003c\/p\u003e\n\n\u003cp\u003eThe \u003ca href=\"\/products\/sonax-xtreme-scheibenklar-glasreiniger\" title=\"SONAX XTREME ScheibenKlar Glasreiniger\"\u003eXTREME ScheibenKlar\u003c\/a\u003e is your all-rounder for manual cleaning: grab the spray bottle, spray the window, wipe with a microfiber cloth – done. It works inside and out and is also suitable for mirrors, headlight glass, and even household windows. Choose this product if you want quickly clean windows without building up a sealing effect. It is also the first choice for interior windows because it does not leave a hydrophobic layer that could promote fogging there. The 500-ml bottle is sufficient for dozens of applications – one spray per quadrant is enough. ScheibenKlar also works for navigation displays and infotainment screens, provided you do not spray it directly onto the screen but onto the cloth – this prevents liquid from running into gaps and ventilation openings.\u003c\/p\u003e\n\n\u003cp\u003eThe \u003ca href=\"\/products\/sonax-xtreme-scheibenreiniger-sommer-wischwasser-gebrauchsfertig\" title=\"SONAX XTREME ScheibenReiniger Sommer\"\u003eXTREME ScheibenReiniger Summer\u003c\/a\u003e comes ready-to-use and goes directly into your vehicle's washer fluid reservoir. It is optimized for the challenges of the warmer months – insect residues, pollen, tree sap, and road dust – and ensures that your wipers glide cleanly across the windshield instead of just smearing dirt. The integrated glide protection also protects the wiper blades. The 3-liter bottle lasts for several weeks, depending on driving performance. Ideal for anyone who wants a functional washer fluid without mixing and wants to keep window care uncomplicated.\u003c\/p\u003e\n\n\u003cp\u003eThe \u003ca href=\"\/products\/sonax-xtreme-scheibenreiniger-1-100-wischwasser-konzentrat\" title=\"SONAX XTREME ScheibenReiniger 1:100\"\u003eXTREME ScheibenReiniger 1:100 Concentrate\u003c\/a\u003e is the economical alternative for frequent drivers and commercial users. 250 ml of concentrate yields up to 25 liters of washer fluid – which is significantly cheaper per liter than any ready-to-use product. The concentration can be adjusted to the season: standard 1:100 for spring and autumn, 1:80 for summer with heavy insect contamination, in winter the higher concentrated mixing ratio provides frost protection. Anyone who maintains many vehicles or manages a fleet cannot do without this concentrate.\u003c\/p\u003e\n\n\u003cp\u003eAnd for those who want to go a step further: The \u003ca href=\"\/products\/sonax-xtreme-ceramic-scheibenklar-2-in-1-glasreiniger-versiegelung\" title=\"SONAX XTREME Ceramic ScheibenKlar 2 in 1\"\u003eXTREME Ceramic ScheibenKlar 2 in 1\u003c\/a\u003e cleans and seals in one step. After application and five minutes of drying time, the ceramic layer creates a lotus effect – raindrops bead off and carry away dirt particles. This significantly reduces cleaning effort between maintenance intervals. The premium option for anyone who wants their windows not only clean but also actively protected. Important: Only apply it to dry exterior windows. For interior windows, the regular ScheibenKlar remains the better choice, as a hydrophobic layer inside the car can promote fogging.\u003c\/p\u003e\n\n\u003ch3\u003eWindow Care in Workflow – How to Use the XTREME Series Correctly\u003c\/h3\u003e\n\n\u003cp\u003eThe most effective workflow with the XTREME window series follows a clear three-step process: basic cleaning, fine cleaning, optional sealing. First, fill one of the washer fluids into your vehicle's windshield washer reservoir – the ScheibenReiniger Summer in the warmer months, the 1:100 concentrate year-round. While driving or during a hand wash, the washer fluid dissolves coarse dirt: insect residues, road dust, salt residues. The windshield wipers distribute the solution and remove the softened dirt. It is important to allow the washer fluid two to three seconds to dwell before the wipers run – this way, the formula breaks down the dirt instead of just moving it around.\u003c\/p\u003e\n\n\u003cp\u003eAfter washing or as an interim cleaning, reach for the XTREME ScheibenKlar: spray thinly onto the window, spread with the \u003ca href=\"\/products\/sonax-profiline-microfasertuch-glas-mikrofasertuch\" title=\"SONAX PROFILINE MicrofaserTuch Glas\"\u003ePROFILINE Microfiber Cloth \"Glass\"\u003c\/a\u003e, wipe with the dry side. Work in strokes from top to bottom – not in circles, as circular movements only redistribute the dirt. For the inside of the windshield, use the same cleaner, but work with the door open – this way you can also reach the hard-to-reach corners of the dashboard. The interior window is often dirtier than expected: plastic outgassing deposits an invisible film on the glass, which only becomes visible as a milky haze when exposed to glare.\u003c\/p\u003e\n\n\u003cp\u003eOptionally, the final step is ceramic sealing with Ceramic ScheibenKlar 2 in 1: spray onto the dry exterior window, spread evenly, and let dry for five minutes. The protective layer lasts several days and significantly extends the intervals between cleanings. If you maintain your vehicle once a week, one Ceramic application per week will result in permanently protected, water-repellent windows. The effect is particularly noticeable in rain: water droplets form beads and are carried away by the wind at medium speeds.\u003c\/p\u003e\n\n\u003cp\u003eFor the ultimate fine-tuning – for example, if windows show blind spots, water stains, or fine scratches after years – the \u003ca href=\"\/products\/sonax-profiline-glasspolish-glaspolitur\" title=\"SONAX PROFILINE GlassPolish Glaspolitur\"\u003eSONAX PROFILINE GlassPolish Glass Polish\u003c\/a\u003e complements the system. It works chemically-mechanically with cerium oxide and micro-finely abrades the damaged glass layer to restore full transparency. After that, the ceramic sealant also adheres better because the surface is smoother and more uniform. This step is only necessary every few months or for visible glass damage – but it can make the difference between \"clean\" and \"like new.\"\u003c\/p\u003e\n\n\u003cp\u003eRegarding frequency: In summer, when insects accumulate on the windshield, manual cleaning with ScheibenKlar is recommended once or twice a week – ideally in the evening, when fresh insect residues are easier to remove than dried ones. The washer fluid works automatically during every drive. In winter, the cleaning frequency is higher (two to three times a week) because salt residues are more aggressive and impair visibility more significantly. The ceramic sealant can be renewed weekly if you want maximum protection – or once a month as basic care. The effort per application is only a few minutes, and the cumulative effect over weeks is noticeable: the windows remain clear longer, the wipers work better, and you brake less often due to poor visibility.\u003c\/p\u003e\n\n\u003cp\u003eAnother aspect many underestimate: the order of care steps influences the result. If you apply the ceramic sealant to an incompletely cleaned window, you seal in the dirt. Therefore, always clean first, then dry, then seal. And wait at least two minutes between ScheibenKlar and Ceramic ScheibenKlar to allow the cleaning formula to evaporate completely before the ceramic particles polymerize.\u003c\/p\u003e\n\n\u003ch3\u003eXTREME Window Care vs. Alternatives – Honest Assessment\u003c\/h3\u003e\n\n\u003cp\u003eCompared to cheap washer fluids from hardware stores, which usually rely on simple isopropanol and water, the XTREME window range offers noticeably more: better gliding for the wiper blades, an anti-resoiling effect that delays re-soiling, and corrosion protection for nozzles and lines. This costs more to purchase but pays off in the long run – wiper blades last longer, and you need to re-clean less often. However, if you are only looking for a simple washer fluid and have no long-term expectations, a hardware store product will also suffice. The difference is mainly noticeable over time: after a few weeks with a cheap washer fluid, you'll notice that the wiper blades wear out faster and the windows have a film again after just a few days. The XTREME formulas were developed to minimize precisely these long-term effects – the result is not only a cleaner window but also noticeably smoother wiper operation.\u003c\/p\u003e\n\n\u003cp\u003eCompared to other premium glass cleaners such as Koch-Chemie GlassCleaner or Gyeon Q²M Glass products, XTREME ScheibenKlar stands out with its Pure-Water-Technology, which is specially optimized for streak-free drying without limescale residues. The Koch-Chemie and Gyeon glass cleaners are more economical as concentrates – those who clean large glass surfaces on many vehicles should compare the cost per liter. However, the real strength of the XTREME series lies in its system concept: no other manufacturer in the consumer sector offers glass cleaner, washer fluid, and ceramic glass sealant as a coordinated product line from a single source. This eliminates compatibility issues and significantly simplifies product selection – you don't have to research whether the cleaner and sealant are compatible.\u003c\/p\u003e\n\n\u003cp\u003eWhen it comes to window sealing, XTREME Ceramic 2in1 clearly distinguishes itself from professional ceramic glass sealants like the \u003ca href=\"\/products\/sonax-profiline-ceramiccoating-cc-glass-scheibenversiegelung\" title=\"SONAX PROFILINE CeramicCoating CC Glass\"\u003eSONAX PROFILINE CeramicCoating \"CC\" Glass\u003c\/a\u003e: The professional sealant lasts up to 12 months but requires careful preparation with glass cleaner and degreaser, as well as professional application under controlled conditions. Ceramic 2in1, on the other hand, is designed for regular maintenance – it can be applied in just a few minutes, but offers a shorter durability. Both have their justification: CC Glass for long-term protection after detailing, Ceramic 2in1 for everyday maintenance between detailing. For most car owners who don't want to perform a professional glass sealant, Ceramic 2in1 is a much more accessible entry into ceramic protection for windows. A sensible middle ground: apply a CC Glass professional sealant once in spring and extend its durability throughout the year with regular Ceramic 2in1 touch-ups. This combines the durability of the professional solution with the ease of use of the consumer variant.\u003c\/p\u003e\n\n\u003ch3\u003eFor whom is the XTREME series for windows and glass ideal?\u003c\/h3\u003e\n\n\u003cp\u003eThe XTREME window care series is aimed at anyone who wants to systematically include windows in vehicle care – not just the paintwork. Detailing enthusiasts use the series as a finishing touch after paint care to complete the overall look with streak-free windows. Everyday drivers appreciate the uncomplicated application: spray ScheibenKlar, wipe, done. Frequent drivers and commuters particularly benefit from the 1:100 concentrate, which costs almost nothing per liter and supplies the washer fluid reservoir for months.\u003c\/p\u003e\n\n\u003cp\u003eCommercial users with a fleet also find the right solution in the series: the concentrate is economical, ScheibenKlar is quickly applied, and the Ceramic 2in1 sealant offers protection that reduces maintenance effort between intervals. And even in the household, XTREME ScheibenKlar replaces conventional window cleaner – Pure-Water-Technology works just as effectively on windows, shower enclosures, and mirrors as it does on car glass. A system that works beyond the garage.\u003c\/p\u003e\u003cp\u003eIf you're unsure where to start: the XTREME ScheibenKlar as a single product is the lowest-threshold entry point. It costs little, is immediately ready for use, and shows you in its first application what differentiates Pure-Water Technology from a normal glass cleaner. From there, you can expand the system piece by piece – with the washer fluid for automatic cleaning on the go and the ceramic sealant for long-term protection. Or you can start directly with all four products and build your complete window care workflow from the beginning. In both cases, you get a system that is coordinated and in which each product has its fixed place.\u003c\/p\u003e\n\n\u003cp\u003eBy the way: Window care is one of the most underestimated aspects of vehicle care. While many car owners invest hours in paint polishing and rim cleaning, windows often remain an afterthought – even though clear windows not only look better but also directly influence driving safety. Glare from smeared interior windows in oncoming light, reduced visibility in rain due to non-beading water, or salt haze on the windshield in winter – all of this can be avoided with proper window care. The XTREME series makes it as easy as possible for you to consistently integrate this often-neglected part of car care into your workflow.\u003c\/p\u003e","products":[{"product_id":"sonax-xtreme-scheibenklar-glasreiniger","title":"XTREME ScheibenKlar Glass Cleaner","description":"\u003ch2\u003eStreak-free vision on any glass — SONAX XTREME ScheibenKlar in everyday use\u003c\/h2\u003e\n\n\u003cblockquote\u003e\n  \u003cp\u003e\u003cem\u003eWhat makes a good car glass cleaner?

Always keep separate microfibre cloths — one for the inside, one for the outside. Spray the cloth, not the glass directly, so you don't overspray onto the dashboard or paint. On the inside, wipe in diagonal passes so any streaks show up straight away and you can go back over them on the spot.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eGreasy film and tobacco deposits on glass — the chemistry behind it, and why a household cleaner won't cut it\u003c\/h3\u003e\n\n\u003cp\u003eThe greasy film on the inside of car windows comes from a mix of sources: outgassing from plastic and leather parts in the cabin, silicone-based dashboard dressings, tobacco smoke, and skin oils from touching the glass as you get in and out. This invisible film holds organic fats and siloxanes that bond firmly to the glass and can't be shifted by water alone, because grease is hydrophobic and water simply won't pick it up.\u003c\/p\u003e\n\n\u003cp\u003eHousehold glass cleaners are often only half-suited to cleaning car windows. Many of them contain ammonia or other chemicals that can damage painted or leather surfaces if you hold the bottle too close or the product spits onto surfaces that aren't built for those chemicals. On top of that, a lot of all-purpose cleaners leave limescale residue that shows up on the glass as it dries. An automotive glass cleaner like ScheibenKlar is tuned to what a car window actually needs.\u003c\/p\u003e\n\n\u003cp\u003eThe season makes a noticeable difference to how much cleaning you need, too. In summer, insect residue and baked-on road spray on the windscreen are the biggest challenge; in winter you add de-icer residue and salt mist that dry on at the bottom edge of the glass and leave a stubborn white film. ScheibenKlar works all year round and handles both scenarios — the formula breaks down organic residue and mineral deposits alike, so you don't need a separate summer and winter product.\u003c\/p\u003e\n\n\u003cp\u003eOne more critical point concerns cars with tinted windows. Cheap glass cleaners with overly aggressive solvents can damage filmed windows or factory tint by softening the film. The \u003ca href=\"\/products\/sonax-xtreme-scheibenklar-glasreiniger\"\u003eSONAX XTREME ScheibenKlar\u003c\/a\u003e is designed to be compatible with automotive glass, tinted windows included. The formula is gentle on window film and tint while still cleaning effectively.\u003c\/p\u003e\n\n\u003cp\u003eA suitable glass cleaner matters for motorhomes, caravans and boats as well: acrylic and polycarbonate glazing, the kind you find in these vehicles, is more sensitive to solvent-based cleaners than classic toughened glass. For surfaces like that, go for a glass cleaner that's rated as compatible with plastic glazing. If you're not sure whether ScheibenKlar suits a particular glazing type, test it first on a small, out-of-the-way spot.\u003c\/p\u003e\n\n\u003ch3\u003eWhere to use it in the car — windscreen, interior cleaning and prep for a glass sealant\u003c\/h3\u003e\n\n\u003cp\u003eThe main job for ScheibenKlar is cleaning the inside of the windscreen and the side windows. These surfaces collect the most greasy film, since they're the most exposed to outgassing from the cabin. Regular cleaning — at least once a month, or whenever your vision is noticeably affected, is the rule of thumb — keeps the glass clear and cuts down the smearing you get when the washer system spreads fluid across already greasy glass instead of clearing it.\u003c\/p\u003e\n\n\u003cp\u003eOn the outside of the windscreen, ScheibenKlar is ideal for getting rid of insect residue, dirt spray and the wiper smears that rubber blades leave on dirty glass. A thorough outside clean of the windscreen makes real sense heading into the winter months, to give de-icers and glass sealants the best possible grip. Clean glass takes a sealant like the \u003ca href=\"\/products\/sonax-xtreme-ceramic-scheibenklar-2-in-1-glasreiniger-versiegelung\"\u003eXTREME Ceramic ScheibenKlar \"2 in 1\"\u003c\/a\u003e far better than a grease-hazed surface ever will.\u003c\/p\u003e\n\n\u003cp\u003eIn professional detailing, ScheibenKlar goes in as the pre-clean step before a glass sealant. Silicone-based glass sealants only bond properly to the glass when no greasy film is blocking the adhesion. A consistent pre-clean with ScheibenKlar makes sure the sealant reaches its full lifespan and the water beading runs evenly across the whole pane.\u003c\/p\u003e\n\n\u003cp\u003eAt dealerships and in valeting, glass cleaning is often one of the last and most telling steps before the car is handed back. A spotless windscreen with no greasy smears or streaking tells the customer at a glance that the work was done with care. Skimp on this final detail and you lose that — but get it right and you leave a lasting impression with a tool that genuinely does what it promises: crystal-clear, streak-free glass that reflects the quality of the whole job and stays in the customer's memory.\u003c\/p\u003e\n\n\u003ch3\u003eTechnique for a streak-free finish — what really matters in glass cleaning\u003c\/h3\u003e\n\n\u003cp\u003eTechnique is what decides the result in glass cleaning. Work the glass in two passes. First pass wet — spray ScheibenKlar onto a microfibre cloth, wet the surface evenly and let the cleaner do its work. Second pass dry — buff the glass off with a second, clean microfibre cloth in crossing strokes. This two-stage approach lifts the greasy film on the first pass and clears it completely on the second.\u003c\/p\u003e\n\n\u003cp\u003eWhen is the glass actually clean? A simple field test gives you the answer: look at the glass against the light, or at a shallow angle to the light source. Haze and grease residue show up straight away as a milky cloudiness that's often invisible head-on. Only once the glass looks evenly clear and transparent from every angle is the job done. This backlight check is the most reliable quality test for glass cleaning and is worth making routine at the end of every window clean.\u003c\/p\u003e\n\n\u003cp\u003eThe inside of the glass calls for one extra note: on big, steeply raked windscreens, cleaning the inside is awkward by design. A cleaning pad with an angled handle, or an extended reach tool that holds the microfibre cloth, makes the work easier in the corners your normal arm reach struggles with. Even, gentle pressure and deliberately overlapping diagonal strokes give you the most reliable result, and the backlight check shows you straight away and unmistakably whether any patches need going over again.\u003c\/p\u003e\n\n\u003cp\u003eA pro tip for the most stubborn kind of greasy film: if a faint haze is still there after two cleaning passes, an extra pass with an IPA-soaked cloth before the ScheibenKlar step can help. IPA cuts through particularly stubborn silicone residue that normal glass cleaners don't fully break down. After the IPA cloth, go over it again as usual with ScheibenKlar — and even years-deep grease comes off as crystal-clear glass with no streaks.\u003c\/p\u003e\n\n\u003cp\u003eOn heavily smeared glass with old, dried-on silicone residue, a second full cleaning pass may be needed. This state often builds up when no suitable glass cleaner has been used for a long time, or when silicone-based dressings like dashboard spray have spat onto the glass. Keep on top of the car regularly with ScheibenKlar and you avoid stubborn deposits forming in the first place, and save yourself those drawn-out multi-pass cleans.\u003c\/p\u003e\n\n\u003cp\u003eOne spot that often gets overlooked is the rear window with its heating elements. When you clean this glass, always wipe along the heating lines — horizontally — never across them. Too much friction across the lines can damage the bond of the printed-on elements on older or already weakened cars. With a well-soaked, soft microfibre cloth and gentle pressure along the lines, the rear window cleans up without a problem too.\u003c\/p\u003e\n\n\u003cp\u003ePicking the right cloth makes a big difference to the result as well. For glass cleaning, microfibre cloths with a short, smooth pile work best, since they leave no fibres behind and give you an even cleaning surface. Cloths with a long pile, the kind that suit drying off or laying down sealants, are less suited to glass — they leave more fibres on the cleaned surface and force an extra buffing step.\u003c\/p\u003e\n\n\u003ch3\u003eScheibenKlar vs. Ceramic ScheibenKlar vs. PROFILINE GlassCleaner — choosing the right glass-cleaning solution\u003c\/h3\u003e\n\n\u003cp\u003eWithin the SONAX glass cleaner range there are several options with different priorities. The XTREME ScheibenKlar is the all-round glass cleaner with no added sealing properties — it cleans reliably and leaves a clean surface that's ready for further care products. It's the right pick when the focus is purely on cleaning, or when a standalone glass sealant is going on next.\u003c\/p\u003e\n\n\u003cp\u003eIf you want to build up your glass-cleaning kit step by step and cost-effectively, you can start with ScheibenKlar as the base and add the Ceramic ScheibenKlar later as a handy upgrade for cars that regularly need a glass sealant. This combination — a pure cleaner for a thorough deep clean, a 2-in-1 product for the quick refresh — covers both scenarios and gives you maximum flexibility in day-to-day work without having to invest in an overly complex range.\u003c\/p\u003e\n\n\u003cp\u003eThe \u003ca href=\"\/products\/sonax-xtreme-ceramic-scheibenklar-2-in-1-glasreiniger-versiegelung\"\u003eXTREME Ceramic ScheibenKlar \"2 in 1\"\u003c\/a\u003e combines cleaning power with a ceramic seal in one step. For anyone who wants to save time and lay down a base seal on the glass at the same time, that's the more efficient option. The cleaning power is a touch less intense than the pure ScheibenKlar, since the formula is tuned for both jobs.\u003c\/p\u003e\n\n\u003cp\u003eFor pros with high glass-cleaning volume, the \u003ca href=\"\/products\/sonax-profiline-glasscleaner-glasreiniger\"\u003ePROFILINE GlassCleaner (concentrate)\u003c\/a\u003e is the more economical alternative. You dilute the concentrate to the strength you want, which brings the cost per car right down. For outfits cleaning a lot of car windows every day, the concentrate is the more professional choice over the ready-to-use ScheibenKlar in the 500 ml spray bottle.\u003c\/p\u003e\n\n\u003ch3\u003eBuying advice — who the XTREME ScheibenKlar is the right pick for\u003c\/h3\u003e\n\n\u003cp\u003eThe \u003cstrong\u003eSONAX XTREME ScheibenKlar\u003c\/strong\u003e is the right pick for car owners and detailers after a reliable, all-round glass clean with no frills. The 500 ml format is ideal for the regular upkeep of one car or several, private or commercial, without needing the economics of a big pro container. If you value clear vision and want to keep haze and streaking out of your line of sight on the move, you've got a dependable tool here for the regular window routine. It's quick and easy to get the hang of — and the result shows the moment you drive into low sun or a night run.\u003c\/p\u003e\n\n\u003cp\u003eAs a verified SONAX stockist, Detailing1 carries ScheibenKlar in the range. If you want to run it as part of a full glass cleaning and care routine, Detailing1 also has every matching add-on from the SONAX line — from the pre-clean through to a long-lasting ceramic seal for car windows.\u003c\/p\u003e\n\n\u003cp\u003eFor fleet operations and outfits running a lot of cars, it's worth checking whether the concentrate format of the PROFILINE GlassCleaner works out cheaper than the ready-to-use product. Across regular use on several cars, the cost difference adds up fast. ScheibenKlar, on the other hand, is the ideal pick for businesses or private users who'd rather have a simple, ready-to-go product with no diluting.\u003c\/p\u003e\n\n\u003cp\u003eIn the end, picking the right glass cleaner comes down to how often you use it and the result you're after. If you clean your car rarely and want maximum simplicity, ScheibenKlar has you perfectly covered. If you professionally detail a lot of cars and want to optimise both cost and result, you can build the SONAX glass cleaner range as a system — with ScheibenKlar as the standard cleaner, the Ceramic ScheibenKlar for sealant upkeep, and the concentrate for high-volume work. As a verified SONAX stockist, Detailing1 is glad to advise on putting together the right glass-cleaning range for your particular business or use case.\u003c\/p\u003e","brand":"SONAX","offers":[{"title":"500ml","offer_id":49160878915919,"sku":"D1-SNX-02382410","price":8.49,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/Sonax-XTREME-ScheibenKlar-4.png?v=1721514350"},{"product_id":"sonax-xtreme-scheibenreiniger-1-100-wischwasser-konzentrat","title":"XTREME ScheibenReiniger 1:100 Screenwash Concentrate","description":"\u003ch2\u003eUp to 25 litres of screenwash from a single bottle — SONAX XTREME ScheibenReiniger 1:100 as a super-concentrate\u003c\/h2\u003e\n\n\u003cblockquote\u003e\n  \u003cp\u003e\u003cem\u003eWhat makes SONAX's screenwash super-concentrate different?

The \u003cstrong\u003eSONAX XTREME ScheibenReiniger 1:100\u003c\/strong\u003e solves that with unusual efficiency: the super-concentrate in its handy 250 ml bottle goes in at 1:100 — that is 2.5 ml per 250 ml of water, or the other way round, one bottle covers 25 litres of washer fluid. That saves you serious space, weight and money compared with the classic ready-to-use screenwash.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003e1:100 dilution — one bottle, up to 25 litres.\u003c\/strong\u003e The extreme dilution ratio is the whole point of this product. Next to a 5-litre jug of ready-to-use screenwash, the 1:100 concentrate takes up a fraction of the shelf space and shipping weight. For detailers and vehicle prep businesses that top up washer tanks on customer cars, the 250 ml bottle means compact storage and precise dosing without decanting large volumes.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStreak-free vision, no smeary residue.\u003c\/strong\u003e The formula is built to break down completely once it dries — no waxy film, no surfactant smears left on the windscreen after the blades pass.

A dirty windscreen slows your reactions, because shapes and hazards show up later through the haze. It gets worse in the rain, when bug remains and road dust mix with water and the blades smear the lot into a greasy film instead of wiping it away. A capable screenwash that is already working inside the washer bottle stops exactly that: it loosens the dirt before the blade arrives and lets the wiper lay down a clean, smear-free sweep — every single time.\u003c\/p\u003e\n\n\u003chr\u003e\n\n\u003cblockquote class=\"praxistipp\"\u003e\n  \u003cp\u003e\u003cstrong\u003eDay-to-day from Detailing1:\u003c\/strong\u003e For the best results, mix the ScheibenReiniger 1:100 straight into the washer bottle: fill the tank with tap water, then add the matching amount of concentrate — for a typical 3-litre tank that is 30 ml. For baked-on bug splatter on the windscreen you can push the concentration up a bit (1:50 to 1:30) — more cleaner then goes to work with every spray-and-wipe. The 250 ml bottle is perfect to grab for the boot on a road trip: it takes up almost no space and carries you through long distances.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eSuper-concentrate technology behind the ScheibenReiniger 1:100 — how it works and why it is formulated this way\u003c\/h3\u003e\n\n\u003cp\u003eThe \u003cstrong\u003eSONAX XTREME ScheibenReiniger 1:100\u003c\/strong\u003e runs a highly concentrated surfactant and cleaner formula that turns into a fully functional washer fluid once you cut it 1:100 with water. The ratio is not arbitrary: the actives are dosed so high that even after a 1:100 dilution there is still enough surfactant, sheeting agent and cleaning substance left to work properly on the windscreen and to flash off with barely any residue.\u003c\/p\u003e\n\n\u003cp\u003eThe streak-free finish comes from sheeting agents (surfactants with hydrophobic behaviour) that spread the water evenly and let it run off in a controlled way. Without them the water would sit on the glass in drops and puddles while you wipe, and dry into smears. The sheeting agents in the ScheibenReiniger 1:100 make sure the wash water spreads thin across the whole pane and dries in one even, smear-free layer.\u003c\/p\u003e\n\n\u003cp\u003eThe super-concentrate logic follows a clear product development principle: the higher the dilution ratio, the less water you ship in the finished product, the smaller the packaging and the less weight there is to transport. With the 1:100 concentrate SONAX brings a format that is already standard in other cleaning categories but is still rare in screenwash — a clear win for high-mileage drivers and for pros who want to free up storage space.\u003c\/p\u003e\n\n\u003cp\u003eFor the hard cases — heavy bug season in summer, salt smear in winter — you can temporarily push the concentration to 1:50 or 1:30. That flexibility, which a ready-to-use product simply cannot give you, lets one bottle of concentrate cover different cleaning intensities and adapt to the season.\u003c\/p\u003e\n\n\u003cp\u003eThe surfactant package in the ScheibenReiniger 1:100 is designed for material compatibility. The ingredients are picked so that the rubber on the wiper blades, the plastic wiper frames and the paint edges around the windscreen surround are not attacked. That is not a given with heavily concentrated formulas — cheap own-brand concentrates sometimes lean on aggressive solvents that can make rubber go brittle. SONAX tests material compatibility systematically during development, which makes it a dependable choice for continuous use in commercial fleets too.\u003c\/p\u003e\n\n\u003ch3\u003eUsing the ScheibenReiniger 1:100 properly — dosing, filling and season by season\u003c\/h3\u003e\n\n\u003cp\u003eDosing the 1:100 concentrate is easy to work out: a 3-litre washer tank takes 30 ml of concentrate, a 5-litre tank 50 ml. A simple kitchen syringe or a graduated dosing bottle gets you the exact amount without weighing anything. In real life you can also go slightly heavier without doing any harm — the ScheibenReiniger 1:100 is generously formulated and takes a moderate overdose in its stride.\u003c\/p\u003e\n\n\u003cp\u003eFor summer duty, where bugs and road dirt dominate, stick with the standard 1:100 dilution. If you are driving through bug-heavy country or down dusty back roads, take it up to 1:70 or 1:50. The \u003ca href=\"\/products\/sonax-xtreme-scheibenreiniger-sommer-wischwasser-gebrauchsfertig\"\u003eSONAX XTREME ScheibenReiniger \"Sommer\"\u003c\/a\u003e is the ready-to-use alternative if you would rather not measure anything at all — but the concentrate gives you far more litres for your money.\u003c\/p\u003e\n\n\u003cp\u003eOnce the tank is filled you can check the fresh screenwash straight away: a quick pull on the wiper stalk with a dry screen tells you whether the concentrate spreads evenly and wipes clear. Too little concentrate and you get smears; get it right and the glass comes up evenly clear. That simple check makes dialling in the dose easy.\u003c\/p\u003e\n\n\u003cp\u003eOn the windscreen, which sits in direct sunlight, streak-free performance really counts. Wiper smears catch the light and can cut your field of vision badly — especially into low sun on an early-morning or evening run. A screenwash that leaves nothing behind once it dries is therefore not a comfort feature but a direct contribution to safety.\u003c\/p\u003e\n\n\u003cp\u003eIf you run the concentrate across a car pool or a commercial fleet, the win is that you define one standard dose per vehicle type and simply repeat it. A small card in the store room listing tank volume and the concentrate quantity per model is all it takes — nobody needs any chemistry knowledge, they just follow the numbers. Training effort drops massively compared with more complex care systems.\u003c\/p\u003e\n\n\u003ch3\u003eWhere the ScheibenReiniger 1:100 fits — all-year use and special cases\u003c\/h3\u003e\n\n\u003cp\u003eThe ScheibenReiniger 1:100 concentrate is built for the summer season above all — it is not an antifreeze and it is not suitable for temperatures below freezing. In summer, when bugs, pollen, exhaust deposits and road dust load up the windscreen, the concentrate is the most efficient route to a clear view. For winter, switch to a screenwash with antifreeze.\u003c\/p\u003e\n\n\u003cp\u003eThe 250 ml bottle is ideal for the glovebox or the boot — an emergency top-up that takes up almost no room. On long trips or drives abroad you simply carry the concentrate and buy water on the way instead of hauling heavy jugs of screenwash around. That travel logic is one of the most practical advantages the super-concentrate has over ready-to-use alternatives.\u003c\/p\u003e\n\n\u003cp\u003eFor prep businesses that top up the washer tank on customer cars as part of the service, the 1:100 concentrate is the economical answer: storing a handful of 250 ml bottles takes far less room than keeping 5-litre jugs on the shelf, and the concentrate is easier to dose and portion out.\u003c\/p\u003e\n\n\u003cp\u003eOne use case that often gets overlooked is the motorhome and camper van. Motorhome drivers cover long distances through very different climates, where bug density and dust load vary wildly. The super-concentrate lets you get through a whole travel season on one small bottle — and tune the concentration to the stretch of road you are on. At the same time the compact format saves a lot of space in the limited storage of a motorhome compared with carrying jugs.\u003c\/p\u003e\n\n\u003ch3\u003eScheibenReiniger 1:100 in comparison — concentrate vs ready-to-use and other products\u003c\/h3\u003e\n\n\u003cp\u003eNext to the \u003ca href=\"\/products\/sonax-xtreme-scheibenreiniger-sommer-wischwasser-gebrauchsfertig\"\u003eready-to-use SONAX XTREME ScheibenReiniger \"Sommer\"\u003c\/a\u003e, the 1:100 concentrate wins clearly on price and storage volume.

For cleaning the screen by hand at services or a petrol station, the ready-to-use summer fluid also works brilliantly as a spray with a microfibre — a splash from the tank in a small container and a \u003ca href=\"\/products\/sonax-profiline-microfasertuch-glas-mikrofasertuch\"\u003eSONAX PROFILINE MicrofaserTuch \"Glas\"\u003c\/a\u003e for a residue-free finish.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eFormulation and technology behind the ready-to-use summer washer fluid\u003c\/h3\u003e\n\n\u003cp\u003eThe \u003cstrong\u003eSONAX XTREME ScheibenReiniger \"Sommer\"\u003c\/strong\u003e is built on a surfactant-water formulation developed specifically for what summer throws at the glass. All-season and winter fluids have to spend part of their chemistry on lowering the freezing point; a pure summer fluid can put every additive into cleaning power and streak-free drying. The result cuts through insect residue, pollen and greasy exhaust particles better than an all-rounder with antifreeze in it.\u003c\/p\u003e\n\n\u003cp\u003eThe streak-free behaviour comes down to specific surfactants that pull the water evenly off the glass after each wipe. These sheeting agents stop the water film from breaking up into isolated drops and puddles that dry into ring-shaped marks. Instead the fluid dries evenly and leaves next to nothing behind — which is exactly what you notice in strong sun, because drying marks show up as blinding streaks against the light.\u003c\/p\u003e\n\n\u003cp\u003eThe formulation is safe on the rubber of the wiper blades, on plastic trim and on the paint around the windscreen. Solvent-heavy budget products attack the wiper lips, shorten their life and wreck the wipe quality. SONAX tests the material compatibility of its washer fluids systematically so the whole system keeps working — something cheap own-brand products often skip entirely.\u003c\/p\u003e\n\n\u003cp\u003eThe 3-litre bottle covers one or two full tank fills, depending on the car. Typical washer bottles hold 2 to 4 litres, so 3 litres sees you all the way through the switch from winter to summer fluid. It comes in a chunky jug with a spout, so you can pour it in without a funnel and without slopping it everywhere. If you've got several cars at home, or you look after customer cars, it's worth keeping two bottles in so the seasonal changeover doesn't stall on a re-order.\u003c\/p\u003e\n\n\u003ch3\u003eUsing the summer washer fluid — filling, changing over and seasonal care\u003c\/h3\u003e\n\n\u003cp\u003eUsing ready-to-use summer washer fluid is about as simple as it gets: open the tank, drain or fully empty the old fluid, pour the bottle straight in. Nothing to measure, nothing to mix, nothing to get wrong. The switch from winter to summer fluid makes sense once the frost season is over — as soon as night-time temperatures stay above 0°C and you no longer need antifreeze. From then on the dedicated summer fluid gives you the best cleaning power against insects and pollen.\u003c\/p\u003e\n\n\u003cp\u003eYou can check it works straight after filling: one quick wipe on a dry screen shows whether the surfactants are wetting the glass evenly. If you're wiping a dirty screen right away, let the fluid sit for a moment before you run the wiper. Dried-on bug splatter in particular benefits from a short 10–30 second soak — it breaks up the protein structure and takes the load off the wiper: fewer streaks, less strain on the blade.\u003c\/p\u003e\n\n\u003cp\u003eIf you run out before summer does, top up with the same product or at least a compatible summer formulation. Mixing different washer fluids is harmless as long as both are solvent-free and made for the same season. Where it gets awkward is mixing winter antifreeze fluid with a pure summer product — the frost protection gets diluted and you're inviting frozen lines next winter. Emptying the tank completely at the changeover is the cleanest way to do it.\u003c\/p\u003e\n\n\u003cp\u003eIf the car runs all year and through changing climates, keep a simple seasonal rule: switch to a winter fluid by the end of October, back to summer fluid by early April at the latest. The ready-to-use 3-litre format covers the spring changeover with one bottle and nothing left over. Come autumn, a fresh bottle of antifreeze fluid — a clean, tidy rotation with nothing sitting on the shelf.\u003c\/p\u003e\n\n\u003ch3\u003eSummer washer fluid for insects, pollen and road grime — what it does in practice\u003c\/h3\u003e\n\n\u003cp\u003eSummer asks something different of your washer fluid than winter does. Winter fluids mainly fight salt and slush residue; in summer the enemy is organic — insect splatter, pollen, tree sap and greasy particles off the road. That stuff sticks differently from mineral grime and needs surfactants that emulsify organic fats and proteins.\u003c\/p\u003e\n\n\u003cp\u003eOn motorways and A-roads, where the bug density peaks in summer, the screen picks up a serious layer of insect splatter within a few hundred kilometres. Without enough cleaning power in the washer fluid, the wiper just smears it around. The SONAX XTREME summer formulation is built so the surfactants get right into the insect matter and emulsify it — the wiper then clears it in one pass without leaving the classic smear film behind.\u003c\/p\u003e\n\n\u003cp\u003ePollen is the other seasonal headache, hitting drivers in spring and early summer. Pollen grains are microscopic, they work their way into the glass and turn into a sticky coating as soon as there's moisture around. The washer fluid has to release those particles and carry them off the glass before the wiper drags them across it. A good summer fluid like the XTREME summer product carries enough surfactant to fully break down pollen residue and hand you back a clear view.\u003c\/p\u003e\n\n\u003ch3\u003eSONAX ScheibenReiniger \"Sommer\" compared — ready-to-use vs. concentrate\u003c\/h3\u003e\n\n\u003cp\u003eIf you're topping up the washer tank all the time and want maximum flexibility, compare the ready-to-use bottle with the \u003ca href=\"\/products\/sonax-xtreme-scheibenreiniger-1-100-wischwasser-konzentrat\"\u003eSONAX XTREME ScheibenReiniger 1:100\u003c\/a\u003e. The concentrate dilutes 1:100 — a 250 ml bottle makes 25 litres of ready-to-use fluid, which is far cheaper per litre. If you look after several cars, get through a lot of fluid, or want to dial the dilution up and down with how dirty things get, the concentrate wins on economics.\u003c\/p\u003e\n\n\u003cp\u003eThe ready-to-use summer product wins whenever simplicity is what counts: nothing to measure, nothing to mix, nothing to get wrong. For drivers who rarely fill the tank themselves, for pros with no dedicated dosing station, or for anyone who just wants a bottle in the boot, the 3-litre jug is the easier call. Both deliver the same SONAX cleaning quality — the difference is purely how much effort filling takes and what it costs you.\u003c\/p\u003e\n\n\u003cp\u003eFor cleaning glass by hand — the inside of the windscreen, or a deep clean of baked-on film — the ready-to-use fluid works fine sprayed onto a microfibre. If you want to go further with glass cleaning and protection, grab the \u003ca href=\"\/products\/sonax-xtreme-scheibenklar-glasreiniger\"\u003eSONAX XTREME ScheibenKlar\u003c\/a\u003e as a dedicated glass cleaner.

The 3-litre bottle is the seasonal-purchase format: fill it once, run the season.\u003c\/p\u003e\n\n\u003cp\u003eIf you're commercial and juggling several cars or bigger volumes, take a look at the concentrate instead. Private drivers with one car who just want a reliable summer fluid with no fuss are well served by the ready-to-use format. Pair the summer fluid for everyday wiping with the SONAX XTREME ScheibenKlar for the occasional deep clean and a SONAX PROFILINE MicrofaserTuch \"Glas\" for glass by hand, and you've got a complete screen-cleaning system for the whole summer.\u003c\/p\u003e\n\n\u003cp\u003eSONAX positions this summer fluid as the way into the XTREME glass-care range — with the promise that the cleaning power holds up whether you drive at weekends or eat up motorway miles. If you actually choose your washer fluid rather than grabbing the first bottle on the petrol-station shelf, the XTREME summer fluid is a sound call: SONAX quality, ready to go, for the whole season.\u003c\/p\u003e","brand":"SONAX","offers":[{"title":"3 liters","offer_id":49160881078607,"sku":"D1-SNX-0272400","price":7.49,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/Sonax-XTREME-ScheibenReiniger-Sommer-gebrauchsfert-0.png?v=1721514301"}],"url":"https:\/\/detiiling1.com\/collections\/sonax-xtreme-scheiben-glas.oembed","provider":"Detailing1","version":"1.0","type":"link"}
